Background: Broad-spectrum antibiotic resistance genes are one of the most common developing resistance genes worldwide. Accordingly, it is of paramount importance to study the extended-spectrum beta-lactamase genes to report them to physicians to select the most appropriate treatment. Objectives: This study aimed to detect three genes of ESBL such as TEM, AmpC, and KPC simultaneously. Methods: Primers were designed for ESBL genes such as TEM, AmpC, and KPC with Genscript software. In this study, control-positive genes were used for the PCR set-up. Fifty isolates of Escherichia coli isolated in the Baqiyatallah Hospital were confirmed and checked by Multiplex PCR. Results: This study revealed that TEM, AmpC, and KPC primers could detect positive control genes. The sensitivity and specificity of the multiplex PCR technique for these genes were 0.001 ng and 100%, respectively. Conclusions: This study revealed that a Multiplex PCR with a sensitivity of 0.001 ng and 100% specificity can detect ESBL genes precisely. Accordingly, the rapid and precise detection of the antibiotic resistance genes and the recommendation of an appropriate treatment pattern can decrease the distribution of antibiotic resistance occurrence and economic cost. |
